CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit and priority of U.S. Provisional Application No. 62/307,336, filed Mar. 11, 2016, entitled “Supplier Management,” the entire contents of which are incorporated herein by reference in its entirety for all purposes.

BACKGROUND

A large number of computing devices used today has led to an even larger amount of data created, stored, and accessed by computing devices. A great deal of the data is useful to many other computing devices. Thus, systems may be used to manage and share data with other computing systems and/or computing devices. For example, an enterprise may have systems that manage and store a collection data that is used across multiple systems, applications, and/or processes associated with the enterprise. In many instances, data is added to or removed from the collection of data. Edits may also be made to existing data in the collection of data. As such, the systems need to ensure that the collection of data used by the systems, applications, and/or processes in the enterprise is correct.

SUMMARY

In some embodiments, a non-transitory machine-readable medium stores a program executable by at least one processing unit of a device. The program receives a request for suppliers associated with a location and a category. The program also identifies a matrix, a hierarchy of locations associated with the matrix, and a hierarchy of categories associated with the matrix. The hierarchy of locations includes a plurality of nodes. Each node in the hierarchy of locations represents a location. The hierarchy of categories includes a plurality of nodes. Each node in the hierarchy of categories represents a category. The matrix is a two-dimensional matrix that includes a plurality of rows and a plurality of columns. Each column of the matrix represents a location in the hierarchy of locations. Each row in the matrix represents a category in the hierarchy of categories. The program further determines a set of suppliers by based on the location, the category, the matrix, the hierarchy of locations, and the hierarchy of categories by identifying a column in the matrix associated with the location, traversing through the rows of the column based on the hierarchy of categories, and including suppliers associated with elements traversed along the traversal in the set of suppliers.

In some embodiments, traversing through the rows of the column based on the hierarchy of categories may include identifying a set of ancestor categories of the category in the hierarchy of categories and traversing through a set of elements of the column that represent the set of ancestor categories.

In some embodiments, the column is a first column. Determining the set of suppliers may further include identifying a second column in the matrix based on the hierarchy of locations, traversing through the rows of the second column based on the hierarchy of categories, and including suppliers associated with elements traversed along the traversal of the second column in the set of suppliers. In some embodiments, identifying the second column in the matrix based on the hierarchy of locations may include identifying an ancestor location of the location in the hierarchy of locations and traversing to a column in the matrix that represents the ancestor location. In some embodiments, the request may be from a computing system that includes master data associated with the set of suppliers.

In some embodiments, a method receives a request for suppliers associated with a location and a category. The method also identifies a matrix, a hierarchy of locations associated with the matrix, and a hierarchy of categories associated with the matrix. The hierarchy of locations includes a plurality of nodes. Each node in the hierarchy of locations represents a location. The hierarchy of categories includes a plurality of nodes. Each node in the hierarchy of categories represents a category. The matrix is a two-dimensional matrix that includes a plurality of rows and a plurality of columns. Each column of the matrix represent a location in the hierarchy of locations. Each row in the matrix represents a category in the hierarchy of categories.

In some embodiments, traversing through the rows of the column based on the hierarchy of categories may include identifying a set of ancestor categories of the category in the hierarchy of categories and traversing through a set of elements of the column that represent the set of ancestor categories.

In some embodiments, the column is a first column. Determining the set of suppliers may further include identifying a second column in the matrix based on the hierarchy of locations, traversing through the rows of the second column based on the hierarchy of categories, and including suppliers associated with elements traversed along the traversal of the second column in the set of suppliers. In some embodiments, identifying the second column in the matrix based on the hierarchy of locations may include identifying an ancestor location of the location in the hierarchy of locations and traversing to a column in the matrix that represents the ancestor location. In some embodiments, the request may be from a computing system that includes master data associated with the set of suppliers.

In some embodiments, a system includes a set of processing units and a non-transitory computer-readable medium storing instructions. The instructions cause at least one processing unit to receive a request for suppliers associated with a location and a category. The instructions also cause the at least one processing unit to identify a matrix, a hierarchy of locations associated with the matrix, and a hierarchy of categories associated with the matrix. The hierarchy of locations includes a plurality of nodes. Each node in the hierarchy of locations represents a location. The hierarchy of categories includes a plurality of nodes. Each node in the hierarchy of categories represents a category. The matrix is a two-dimensional matrix that includes a plurality of rows and a plurality of columns. Each column of the matrix represents a location in the hierarchy of locations. Each row in the matrix represents a category in the hierarchy of categories. The instructions further cause the at least one processing unit to determine a set of suppliers by based on the location, the category, the matrix, the hierarchy of locations, and the hierarchy of categories by identifying a column in the matrix associated with the location, traversing through the rows of the column based on the hierarchy of categories, and including suppliers associated with elements traversed along the traversal in the set of suppliers.

In some embodiments, traversing through the rows of the column based on the hierarchy of categories may include identifying a set of ancestor categories of the category in the hierarchy of categories and traversing through a set of elements of the column that represent the set of ancestor categories.

In some embodiments, the column is a first column. Determining the set of suppliers may further include identifying a second column in the matrix based on the hierarchy of locations, traversing through the rows of the second column based on the hierarchy of categories, and including suppliers associated with elements traversed along the traversal of the second column in the set of suppliers.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerous examples and specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention as defined by the claims may include some or all of the features in these examples alone or in combination with other features described below, and may further include modifications and equivalents of the features and concepts described herein.

Described herein are techniques for managing master data. In some embodiments, a system is provide that manages modification to master data of other systems. Such a system may store copies of the master data of the other systems and synchronizes the copies of the master data with the master data stored in the other systems. The system may receive requests from suppliers to modify data in the master data associated with the supplier. In some embodiments, the system employs rules to determine operations to validate the modification.

In some embodiments, the system organizes suppliers according to locations and categories associated with the suppliers. For example, the system may use a matrix and defined hierarchies to manage and identify suppliers based on the locations and categories associated with the suppliers. The system may manage processes for qualifying candidate suppliers that includes sending questions to the candidate suppliers. In some embodiments, the system dynamically generates an aggregate collection of questions from different defined sets of questions based on a location and category for which the candidate supplier is requested to be qualified.

FIG. 1 illustrates a system 100 for managing master data according to some embodiments. As shown, system 100 includes computing systems 105 a-n, master data manager 115, supplier network manager 150, validation system 160, client devices 165 a-k, and storages 170-185. As illustrated in FIG. 1, each computing system 105 includes a master data storage 110 that is managed by the corresponding computing system 105. Each master data storage 110 is configured to store master data. Each computing system 105 is configured to synchronize master data stored in a master data storage 110 managed by the computing system 105 with a copy of the master data managed by master data manager 115. If master data manager 115 does not have a copy of the master data, computing system 105 sends master data manager 115 a copy of the master data.

In some embodiments, master data includes data associated with the computing system 105 that manages the master data. Master data may also include data associated with other systems. For example, master data includes data associated with one or more suppliers with which computing system 105 participates in transactions. Such data may be referred to as supplier master data or vendor master data. In some embodiments, supplier master data includes, for a particular supplier, legal information (e.g., supplier name, address, contact information, tax identifier (ID), etc.), financial information (e.g., bank details, payment terms, etc.), procurement information (e.g., a location at which orders are received, a method of ordering, an address for ordering, an address for invoicing, etc.), line of business information (e.g., information associated with manufacturing, information associated with retail, etc.), etc. Each master data storage 110 may store supplier master data associated with any number of different suppliers. Different master data storages 110 may store supplier master data associated with the same, similar, and/or different suppliers.

Supplier network manager 150 manages a platform that facilitates transactions between users of computing systems 105 a-n (e.g., buyers) and users of client devices 165 a-k (e.g., suppliers or vendors). In some embodiments, supplier network manager 150 provides an interface (e.g., a web portal) through which users of client devices 165 a-k manage and store information associated with suppliers (e.g., supplier information), items (e.g., goods and/or services) the suppliers are offering for sale to users of computing systems 105 a-n, purchases of items, invoicing for the purchases, request for quotes (RFQs) for items, etc. In some embodiments, supplier network manager 150 and master data manager 115 are implemented on the same computing system (e.g., a cloud computing system). In other embodiments, supplier network manager 150 and master data manager 115 are implemented on separate systems.

As shown, supplier network manager 150 includes supplier data storage 155, which is configured to store data associated with suppliers (also referred to as supplier data). The information stored in supplier data storage 155 includes the same or similar data as supplier master data stored in master data storages 110 a-n. For example, supplier data storage 155 may include, for a particular supplier, legal information (e.g., supplier name, address, contact information, tax ID, etc.), financial information (e.g., bank details, payment terms, etc.), procurement information (e.g., a location at which orders are received, a method of ordering, an address for ordering, an address for invoicing, etc.), etc.

In some embodiments, the fields for storing data in supplier data storage 155 are different than the fields for storing the same or similar data in master data storages 110 a-n. For instance, a bank account number and a routing number may be stored in supplier data storage 155 in the fields “account number” and “routing number” while a bank account number and a routing number may be stored in a master data storage 110 in the fields “bank details 1” and “bank details 2.” Furthermore, different computing systems 105 a-n may store the same or similar supplier data in master data storages 110 a-n using different fields in some embodiments. Continuing with the example, different computing systems 105 a-n may store a bank account number and a routing number in master data storages 110 a-n using different fields.

Client devices 165 a-k are configured to access and communicate with supplier network manager 150. For instance, a user (e.g., an employee of a supplier, etc.) may use a client device 165 to access and manage, through the interface provided by supplier manager network 150, information associated with the supplier, items (e.g., goods and/or services) the supplier is offering for sale to users of computing systems 105 a-n, purchases of items, invoicing for the purchases, request for quotes (RFQs) for items, etc.

Master data manager 115 is responsible for managing master data that is synchronized with master data stored in computing systems 105 a-n. As shown in FIG. 1, master data manager 115 includes master data storage copies 120 a-n, modification manager 125, validation engine 130, and modification rule storage 135. Master data storage copy 120 a-n are copies of master data stored in the corresponding master data storages 110 a-n of computing systems 105 a-n. If master data manager 115 does not have a copy of master data from a particular computing system 105, master data manager 115 sends the particular computing system 105 a request for a copy of the master data. Upon receiving the copy of master data, master data manager 115 stores the copy in a corresponding master data storage copy 120 and synchronizes the master data stored in the master data storage copy 120 with the master data stored in the corresponding master data storage 110.

Master data manager 115 may receive requests from supplier network manager 150 to modify data in master data. In response to such requests, master data manager 115 sends the request to modification manager 125 for processing. In some instances, master data manager 115 may receive notifications from modification manager 125 of modifications to master data copy storages 120 a-n. In response to such notifications, master data manager 115 sends notifications to corresponding computing systems 110 to update the respective master data storages 110 and notifications to supplier network manager 150 that requested modifications to the master data have been applied. In other instances, master data manager 115 may receive notifications from modification manager 125 that a request to modify master data is not valid. In response to these notifications, master data manager 115 sends notifications to supplier network manager 150 indicating that the request to modify master is denied.

Modification manager 125 handles requests to modify master data. When modification manager 125 receives a requests from master data manager 115 to process a request to modify master data, modification manager 125 forwards the request to, and instructs, validation engine 130 to validate the modification request. If validation engine 130 informs modification manager 125 that the new value is valid, modification manager 125 modifies master data in one or more master data copy storages 120 a-n and notifies master data manager 115 of the modifications. Otherwise, modification manager 125 notifies master data manager 115 that the new value is not valid.

As mentioned above, in some embodiments, different computing systems 105 a-n may store the same or similar supplier data in master data storages 110 a-n using different fields. In some embodiments, master data modification rules are used to process requests to modify data in master data storages 110 a-n. In some embodiments, a master data modification rule includes a supplier identifier (ID) associated with a particular supplier; a mapping between a field in the master data stored in a master data storage 110 and a field of supplier data stored in supplier data storage 155 associated with the particular supplier; and a set of validation operations that are performed when a modification to the field in the supplier data is requested.

In some embodiments, users of computing systems 105 a-n create modification rules and send the modification rules to master data manager 115 to store in modification rule storage 135. For example, master data manager 115 may provide a form (e.g., via a graphical user interface (GUI)) for creating a master data modification rule to a user of a computing system 105. The form includes the fields of supplier data. The user may select a supplier/supplier ID and a field in the master data that corresponds to a field of the supplier data. Using the example described above, the master data stored in a master data storage 110 may use a field “bank details 1” to store a bank account number of a supplier while supplier data uses a field “account number” to store its band account number. The user in such an example selects the field “account number” from the fields of the supplier data to map to the “bank details 1” field of the master data. Next, the user may specify a set of validation operations that are performed when the “account number” field in the supplier data is requested to be modified. Once the user has created the master data validation rule, computing system 105 sends the master data modification rule to master data manager 115 for storage. In some embodiments, the set of validation operations includes a sending a request to validation system 160 to validate the modification. In other embodiments, the set of validation operations includes requesting a user of computing system 105 to provide approval for the modification.

Validation engine 130 is responsible for processing requests to validate modifications to master data. For instance, validation engine 130 may receive a request from modification manager 125 to validate a request to modify master data stored in a master data storage 110. The request specifies a new value for a field in supplier data associated with a particular supplier. Validation engine 130 then accesses modification rule storage 135 to identify one or more master data validation rules that includes a mapping that specifies the particular field of supplier data associated with the particular supplier. For each identified master data validation rule, validation engine 130 executes the set of validation operations specified in the master data validation rule. If the new value is a valid value based on the result of the set of validation operations of a particular master data modification rule, validation engine 130 identifies a master data storage based on the mapping of the master data modification rule and sends modification manager 125 a request to modify the field in the identified master data storage, the supplier ID specified in the master data modification rule, and the new value. Otherwise, validation engine 130 informs modification manager 125 that the new value is not a valid value.

Validation system 160 is configured to provide automated validation to modifications to master data stored in master data storage 110 a-n. Validation system 160 may receive a request from validation engine 130 to validate a new value for a particular field in a master data storage 110 a-n. In some embodiments, the request also includes data associated with the supplier with which the particular field is associated. For example, if validation system 160 receives a request to validate a new bank account number for a supplier, such a request may include the name of the supplier, the address of the supplier, the tax identifier of the supplier, etc. Validation system 160 determines whether the new value requested for the particular field is a valid value based on the data associated with the supplier that is included in the request. Validation system 160 then sends validation engine 130 a notification of the result of the determination (e.g., the new value is a valid value or the new value is not a valid value). In some embodiments, validation system 160 is a system (e.g., a third party system) separate from a system on which master data manager 115 is implemented. In other embodiments, validation system 160 and master data manager 115 are implemented on the same system.

FIG. 2 illustrates an example data flow through the system illustrated in FIG. 1 according to some embodiments. Specifically, FIG. 2 illustrates a data flow of a user of a client device requesting modification to a field of supplier data associated with a particular supplier. The data flow starts by a user of client device 165 k sending, at operation 205, supplier network manager 150 a request to modify a field of supplier data associated with a particular supplier. In this example, the request is to modify a “bank account” field of supplier data associated with the particular supplier with a new bank account number. In some embodiments, the user of client device 165 k sends the request through a GUI provided by supplier network manager 150 that the user of client device 165 k uses to access and manager supplier data associated with the supplier.

When supplier network manager 150 receives the request, supplier network manager 150 forwards, at operation 210, the request to master data manager 115. Upon receiving the request from supplier network manager 150, master data manager 115 accesses sends the request to modification manager 125 for processing. After receiving the request from master data manager 115, modification manager 125 sends, at operation 215, the request to validation engine 130 and instructs validation engine 130 to validate the request. In response to the instructions, validation engine 130 accesses modification rule storage 135 and identifies one or more master data validation rules that includes a mapping that specifies the particular field of supplier data associated with the particular supplier. For this example, validation engine 130 identifies master data modification rule 200, which specifies a supplier ID of “Supplier Y,” a mapping between a “Bank Details 1” field in master data stored in master data storage 110 b and a “Account Number” field of data stored in supplier data storage 155 associated with Supplier Y; and a set of validation operations that includes sending a request to validation system 160.

As specified in master data validation rule 200, validation engine 130 sends, at operation 220, validation system 160 a request to validate the new bank account number for the “bank account” field along with data associated with Supplier Y (e.g., the name of the supplier, the address of the supplier, the tax identifier of the supplier, etc.). When validation system 160 receives the request along with the data associated with Supplier Y, validation system 160 determines whether the new bank account number is valid based on the data associated with Supplier Y. In this example, validation system 160 determines that the new bank account number is valid and sends, at operation 225, validation engine 130 a notification indicating so.

When validation engine 130 receives the notification, validation engine 130 identifies master data storage 110 b based on the mapping specified in master data modification rule 200 and sends, at operation 230, modification manager 125 a request to modify the “Bank Details 1” field in master data storage 110 b, the supplier ID (e.g., Supplier Y in this example) specified in master data modification rule 200, and the new bank account number. Upon receiving such information from validation engine 130, modification manager 125 modifies the master data stored in master data copy 120 b, which is a copy of master data storage 110 b. Specifically, modification manager 125 updates, at operation 235, the “Bank Details 1” field in master data storage 120 b associated with Supplier Y, based on the supplier ID, with the new bank account number. Modification manager 125 then notifies master data manager 115 of the modification to master data storage 120 b. In response, master data manager 115 sends, at operation 240, a notification to computing systems 110 b to update master data storage 110 b with the new bank account number for the “Bank Details 1” field associated with Supplier Y and sends, at operation 245, a notification to supplier network manager 150 that the request modification has been applied to the master data.

The data flow shown in FIG. 2 demonstrates an example of modifying a field of master data stored in a master data storage of a computing system in response to a request to modify a field of supplier data. In some embodiments, a user of a client device may request modification to a field of supplier data be applied to a selected set of computing systems. For example, the user of client device 165 k in the example illustrated in FIG. 2 may include in the request sent to supplier network manager 150 a list of master data storages 110 (e.g., a list of master data storage IDs). Thus, when validation engine 130 accesses modification rule storage 135, validation engine 130 identifies master data modification rules that include a mapping between a field in a master data storage 110 included in the list and the particular field of supplier data associated with the particular supplier. This way, the user of client device 165 k may control which computing systems 105 to apply the requested modification.

FIG. 3 illustrates a process 300 for managing master data according to some embodiments. In some embodiments, master data manager 115 performs process 300. Process 300 starts by receiving, at 310, a copy of master data from a first system. Referring to FIG. 1 as an example, process 300 may receive a copy of master data stored in a master data storage 110 of a computing system 105. In some embodiments, the master data includes data associates with one or more suppliers.

Next process 300 receives, at 320, a master data modification rule from the first system. As mentioned above, a master data modification rule may include a supplier ID associated with a particular supplier; a mapping between a field in the master data stored in a master data storage 110 and a field of supplier data stored in supplier data storage 155 associated with the particular supplier; and a set of validation operations that are performed when a modification to the field in the supplier data is requested. Referring to FIG. 2 as an example, the master data modification rule may be master data modification rule 200.

Process 300 then receives, at 330, from a second system, a request to modify a field of supplier data stored in the second system. Referring to FIG. 2 as an example, the request may be the request sent by the user of client device 165 k to supplier network manager 150 and process 300 receives the request from supplier network manager 150.

In response to the request, process 300 identifies, at 340, the master data modification rule. In some embodiments, process 300 accesses a storage (e.g., modification rule storage 1350) configure to store master data modification rules to identify the master data modification rule. Next, process 300 performs, at 350, the set of validation operations specified in the master data modification rule. As explained above, in some embodiments, a set of validation operations may include sending a request to a validation system (e.g., validation system 160) to validate the modification while, in other embodiments, a set of validation operations may include requesting a user of a computing system (e.g., a computing system 105) to provide approval for the modification.

Process 300 then modifies, at 360, the first field in the copy of the master data based on the performance of the set of validation operations. In some embodiments, process 300 modifies the first field in the copy of the master data when the set of validation operations determines that a new value for the first field in the master data is valid. Finally, process 300 sends, at 370, a request to the first system to modify the first field of the master data based on the performance of the set of validation operations. In some embodiments, process 300 sends the request to the first system when the set of validation operations determines that a new value for the first field in the master data is valid. This way, the first system may modify the first field of the master data managed by the first system thereby maintaining synchronization between the master data and the copy of the master data.

As described above, a master data storage 110 of a computing system 105 may include supplier master data associated any number of different suppliers. In some instances, a user of a computing system may wish for a list of suppliers offering a type of item at a given location. In some embodiments, supplier network manager 150 organizes suppliers according to locations associated with the suppliers and categories associated with suppliers. A location associated with a supplier may represent an area or region in which the supplier sells items. A category associated with a supplier may represent a type of item offered by the supplier for procurement. Classifying suppliers according to locations and categories allows supplier network manager 150 to provide different list of suppliers based on different locations and categories.

In some embodiments, supplier network manager 150 organizes suppliers based on locations and categories using a two-dimensional matrix. Supplier network manager 150 may use different matrices to organize suppliers associated with supplier master data stored in different master data storages 110. For instance, supplier network manager 150 may use a first matrix to organize suppliers associated with supplier master data stored in a master data storage 110 a, a second matrix to organize suppliers associated with supplier master data stored in a master data storage 110 b, a third matrix to organize suppliers associated with supplier master data stored in a master data storage 110 c, etc. Supplier network manager 150 may manage and store matrices in supplier matrices storage 170.

FIG. 4 illustrates an example two-dimensional matrix 400 used to organize suppliers according to some embodiments. As shown, matrix 400 includes columns 405-460 and rows 465-495. Each of the columns 405-460 represents a location, which is a geographical area or region. Each of the rows 465-495 represents a category, which is a type of item. Matrix 400 also includes 5 values stored in matrix 400. S1 represents a supplier that sells IT items across the world. S2 represents a supplier that sells IT equipment in North America. S3 represents a supplier that sells desktops in California. S4 represents a supplier that sells laptops in USA. S5 represents a supplier that sells network security across the world.

Supplier network manager 150 may use, in some embodiments, a defined hierarchy of locations and a defined hierarchy of categories to traverse a two-dimensional matrix and identify suppliers. Supplier network manager 150 may use different hierarchies of categories and locations for each matrix. For instance, supplier network manager 150 may use a first hierarchy of categories and a first hierarchy of locations to traverse a first matrix, a second hierarchy of categories and a second hierarchy of locations to traverse a second matrix, a third hierarchy of categories and a third hierarchy of locations to traverse a third matrix, etc. Supplier network manager 150 may manage and store defined hierarchies of categories in category hierarchies storage 175 and defined hierarchies of locations in location hierarchies storages 180. While FIGS. 1 and 2 show storages 170-180 external to suppler network manager 150, one of ordinary skill in the art will understand that one or more storages 170-180 may be part of supplier network manager 150 in some embodiments.

FIGS. 5 and 6 illustrate examples of defined hierarchies that are used to traverse the matrix illustrated in FIG. 4 according to some embodiments. In particular, FIG. 5 illustrates an example hierarchy of locations 500 according to some embodiments. As shown, hierarchy of locations 500 includes nodes 505-560 that represent the different locations illustrated in matrix 400. For this example hierarchy of locations 500, the locations are organized according to geographical areas and/or regions.

As illustrated, node 505 represents a world or global area (e.g., earth). Nodes 510 and 515 are children of node 505 that represent North America and South America regions, respectively. Nodes 520 and 525 are children nodes of node 510 that represent USA and Canada regions, respectively. Nodes 530 and 535 are children nodes of node 515 that represent Brazil and Columbia regions, respectively. Nodes 540 and 545 are children nodes of 520 that represent California and Nevada regions, respectively. Nodes 550 and 555 are children of node 540 that represent San Francisco and Los Angeles regions, respectively. Node 560 is a child of node 545 that represents a Las Vegas region.

In this example, each child node represents a sub-area of sub-region in the region represented by the parent node. Thus, a supplier that is associated with a location in the hierarchy of locations 500 indicates that the supplier sells items in the area or region associated with the location as well as any sub-areas or sub-regions of the location. For example, a supplier that is associated with the USA location indicates that the supplier sells items in the USA location as well as the California, Nevada, San Francisco and Los Angeles locations (i.e., descendants of the USA location in the hierarchy of locations 500).

FIG. 6 illustrates an example hierarchy of categories 600 according to some embodiments. As illustrated, hierarchy of categories 600 includes nodes 605-635 that represent the different categories illustrated in matrix 400. As shown, node 605 represents an IT category. Nodes 610 and 615 are children of node 605 that represent an IT services category and an IT equipment category, respectively. Node 620 is a child node of node 610 that represents a network security category. Nodes 625-635 are children nodes of node 615 that represent a laptop category, a desktop category, and a printer category, respectively.

In this example hierarchy of categories 600, the categories are organized such that each child node represents a sub-category of the category represented by the parent node. As such, a supplier that is associated with a category in the hierarchy of categories 600 indicates that the supplier sells a category of items as well as any sub-categories of items. For instance, a supplier that is associated with the IT Equipment category indicates that the supplier sells IT equipment items as well as the laptop, desktop, and printer items (i.e., descendants of the IT equipment category in the hierarchy of categories 600).

FIG. 7 illustrates a process 700 for identifying suppliers according to some embodiments. In some embodiments, supplier network manager 150 performs process 700. Process 700 will be described by reference to FIGS. 4-6. Process 700 starts by receiving, at 710, a request for suppliers associated with a location and a category. In some embodiments, process 700 receives the request from a user of a computing system 105. For the following example, the request is for suppliers associated with the USA location and the laptop category.

Next, process 700 identifies a matrix, a hierarchy of categories associated with matrix, and a hierarchy of locations associated with the matrix. As explained above, supplier network manager 150 may use different matrices to organize suppliers associated with supplier master data stored in different master data storages 110. As such, process 700 may identify the matrix, the hierarchy of categories, and the hierarchy of locations by accessing storages 170-180. Continuing with the example above, process 700 identifies matrix 400, hierarchy of locations 500, and hierarchy of categories 600.

Finally, process 700 determines, at 730, a set of suppliers based on the matrix, the hierarchy of categories, and the hierarchy of locations. In some embodiments, process 700 determines the set of suppliers by identifying the element in the matrix associated with the location and the category and traversing through the matrix according the hierarchy of categories and the category of locations. In different embodiments, process 700 uses different techniques for determining the set of suppliers. The following will describe one technique.

Continuing with the above example, process 700 may determine the set of suppliers by first identifying the element in matrix 400 associated with the USA location and the laptop category. FIGS. 8A-8F illustrate an example traversal through matrix 400 illustrated in FIG. 4 based on the hierarchies illustrated in FIGS. 5 and 6 according to some embodiments. As illustrated in FIG. 8A, the element in this example is at column 420 and row 485 of matrix 400, as highlighted in FIG. 8A. If any suppliers are associated with this element, process 700 includes the suppliers in the set of suppliers. According, process 700 includes supplier S4 in the set of suppliers for this example.

Next, process 700 identifies the ancestors of the category based on the hierarchy of categories 600. Specifically, process 700 identifies the category in the hierarchy of categories 600 and traverses up the hierarchy of categories 600 to identify ancestor categories of the category. In this example, process 700 identifies the IT equipment category and the IT category as the ancestors of the laptop category. Process 700 then traverses the rows of the current column in matrix 400 according to the identified ancestor categories and identifies any suppliers associated with the elements along the traversal. For this example, process 700 traverses from the element at column 420 and row 485 to the element at column 420 and row 475 (IT equipment in the USA) and then to the element at column 420 and row 465 (IT in the USA), as illustrated in FIG. 8B. If any suppliers are associated with any of the traversed elements, process 700 includes the suppliers in the set of suppliers. Since there are no suppliers at these elements in this example, process 700 does not include any suppliers in the set of suppliers.

To determine the next element to which process 700 traverses, process 700 identifies a parent location of the current location based on the hierarchy of locations 500. In particular, process 700 identifies the current location in the hierarch of locations 500 and traverses up the hierarchy of locations 500 to identify the parent location. For this example, process 700 identifies the North America location as the parent of the USA location. Process 700 then traverses to the element in the matrix associated with the parent location and the requested category. As illustrated in FIG. 8C, process 700 traverses to the element at column 410 and row 485 (laptops in North America) in matrix 400 in this example.

Next, process 700 traverses the rows of column 410 in a similar manner as traversing the rows of column 420. That is, process 700 identifies the ancestors of the category based on the hierarchy of categories 600, traverses the rows of the current column in matrix 400 according to the identified ancestor categories, and identifies any suppliers associated with the elements along the traversal. In this example, process 700 traverses from the element at column 410 and row 485 to the element at column 410 and row 475 (IT equipment in North America) and then to the element at column 410 and row 465 (IT in North America), as shown in FIG. 8D. Again, if any suppliers are associated with any of the traversed elements, process 700 includes the suppliers in the set of suppliers. For this example, process 700 includes supplier S2 in the set of suppliers.

Process 700 determines the next element to traverse to in a similar way as described above. That is, process 700 identifies a parent location of the current location based on the hierarchy of locations 500 and then traverses to the element in the matrix associated with the parent location and the requested category. For this example, the Norther America location is the current location so process 700 identifies the world location as the parent of the North America location based on the hierarchy of locations 500. Thus, process 700 traverses to the element at column 405 and row 485 (laptops in the world) in matrix 400 in this example, as shown in FIG. 8E.

Process 700 then traverses the rows of column 405 in a similar manner as traversing the rows of columns 420 and 410. That is, process 700 identifies the ancestors of the category based on the hierarchy of categories 600, traverses the rows of the current column in matrix 400 according to the identified ancestor categories, and identifies any suppliers associated with the elements along the traversal. For this example, process 700 traverses from the element at column 405 and row 485 to the element at column 405 and row 475 (IT equipment in the world) and then to the element at column 405 and row 465 (IT in the world), as illustrated in FIG. 8F. Again, if any suppliers are associated with any of the traversed elements, process 700 includes the suppliers in the set of suppliers. In this example, process 700 includes supplier S1 in the set of suppliers.

Process 700 determines the next element to traverse to in a similar way as described above. That is, process 700 identifies a parent location of the current location based on the hierarchy of locations 500 and then traverses to the element in the matrix associated with the parent location and the requested category. In this example, the world location is the current location and there is no parent location of the world location based on the hierarchy of locations 500. Therefore, process 700 determines the set of supplies as the suppliers associated with the elements traversed during the traversal through matrix 400. In this example, the set of suppliers includes suppliers S4, S2 and S1.

As discussed above, supplier network manager 150 uses a two-dimensional matrix to organize suppliers based on locations and categories associated with the suppliers. In some embodiments, supplier network manager 150 adds suppliers to a matrix through a qualification process. A supplier may be qualified for a particular location and a particular category. When a supplier is qualified for a particular location and a particular category, the supplier is associated with the particular location and the particular category and supplier network manager 150 adds the supplier to the element in the matrix associated with the particular location and the particular category.

In some embodiments, a qualification process may include supplier network manager 150 sending a candidate supplier (e.g., a user of a client device 165), one or more sets of questions. A set of question may include any number of different questions that prompt the candidate supplier for answers. Different sets of questions may be sent to a candidate supplier when qualifying the candidate supplier for different locations and different categories. In some embodiments, supplier network manager 150 may dynamically generate an aggregate collection of questions based on the location and category for which a candidate supplier is requested to be qualified.

In some embodiments, supplier network manager 150 organizes sets of questions based on locations and categories using a two-dimensional matrix. Each computing system 105 may define different sets of questions based on different locations and different categories and send the defined sets of questions to supplier network manager 150. Supplier network manager 150 may manage and store the defined sets of questions in question sets storage 185. While FIGS. 1 and 2 show storage 185 external to suppler network manager 150, one of ordinary skill in the art will understand that storages 185 may be part of supplier network manager 150 in some embodiments.

Supplier network manager 150 may use different matrices to organize sets of questions defined by different computing systems 105. For example, supplier network manager 150 may use a first matrix to organize sets of questions defined by computing system 110 a, a second matrix to organize sets of questions defined by computing system 110 b, a third matrix to organize sets of questions defined by computing system 110 c, etc. Supplier network manager 150 may manage and store such matrices in supplier matrices storage 170.

FIG. 9 illustrates an example two-dimensional matrix 900 used to organize sets of questions according to some embodiments. As shown, matrix 900 includes columns 905-960 and rows 965-495, which are the same as columns 405-460 and rows 965-999, respectively. Matrix 900 also includes multiple values stored in matrix 900.

For this example, a first set of questions (QS1) have been defined for all categories in the Brazil location. Thus, QS1 is stored in each element in column 930, which represents the location Brazil. A second set of questions (QS2) have been defined for the IT service category in all locations. As such, QS2 is stored in each element in row 970, which represents the IT service category. A third set of questions (QS3) have been defined for the network security category in the California location. Therefore, QS3 is stored in the element at column 940, which represents the California location, and row 980, which represents the network security category. A fourth set of questions (QS4) have been defined for the printer category in the USA location. Thus, QS4 is stored in the element at column 920, which represents the USA location, and row 995, which represents the printer category.

In some embodiments, supplier network manager 150 may use a defined hierarchy of locations and a defined hierarchy of categories to traverse a two-dimensional matrix and identify suppliers. Supplier network manager 150 may use different hierarchies of categories and locations for each matrix. For instance, supplier network manager 150 may use a first hierarchy of categories and a first hierarchy of locations to traverse a first matrix, a second hierarchy of categories and a second hierarchy of locations to traverse a second matrix, a third hierarchy of categories and a third hierarchy of locations to traverse a third matrix, etc. Supplier network manager 150 may manage and store defined hierarchies of categories in category hierarchies storage 175 and defined hierarchies of locations in location hierarchies storages 180.

FIGS. 10 and 11 illustrate examples of defined hierarchies that are used to traverse the matrix illustrated in FIG. 9 according to some embodiments. In particular, FIG. 10 illustrates an example hierarchy of locations 1000 according to some embodiments. As shown, hierarchy of locations 1000 includes nodes 1005-1060 that represent the different locations illustrated in matrix 900. For this example hierarchy of locations 1000, the locations are organized according to geographical areas and/or regions. Nodes 1005-1060 represent the same locations as nodes 505-560 shown in FIG. 5.

For this example, each child node represents a sub-area of sub-region in the region represented by the parent node. In some embodiments, when a candidate supplier is requested to be qualified for a location, supplier network manager 150 sends the candidate supplier questions associated with the location as well questions associated with any sub-areas or sub-regions of the location. For instance, when a candidate supplier is requested to be qualified for the South America location, supplier network manager 150 sends questions associated with the South America location as well as questions associated with the Brazil and Columbia locations (i.e., descendants of the South America location in the hierarchy of locations 1000).

FIG. 11 illustrates an example hierarchy of categories 1100 according to some embodiments. As illustrated, hierarchy of categories 1100 includes nodes 1105-1135 that represent the different categories illustrated in matrix 400. Nodes 1105-1135 represent the same categories as nodes 605-635 illustrated in FIG. 6.

For this example hierarchy of categories 1100, the categories are organized such that each child node represents a sub-category of the category represented by the parent node. In some embodiments, when a candidate supplier is requested to be qualified for a category, supplier network manager 150 sends the candidate supplier questions associated with the category as well questions associated with any sub-categories. For example, when a candidate supplier is requested to be qualified for the IT equipment category, supplier network manager 150 sends questions associated with the IT equipment category as well as questions associated with the laptop, desktop, and printer categories (i.e., descendants of the IT equipment category in the hierarchy of categories 1100).

FIG. 12 illustrates a process 1200 for generating an aggregate collection of questions according to some embodiments. In some embodiments, supplier network manager 150 performs process 1200. Process 1200 will be described by reference to FIGS. 9-11. Process 1200 starts by receiving, at 1210, from a computing system, a request to qualify a candidate supplier for a location and a category. The request to qualify the candidate supplier may, in some embodiments, include a request for questions associated with the location and the category. In some embodiments, process 1200 receives the request from a user of a computing system 105. For the following example, the request is to qualify a candidate supplier for the California location and the IT category.

Next, process 1200 identifies a matrix, a hierarchy of categories associated with matrix, and a hierarchy of locations associated with the matrix. As explained above, supplier network manager 150 may use different matrices to organize sets of questions defined by different computing systems 105. Thus, process 1200 may identify the matrix, the hierarchy of categories, and the hierarchy of locations by accessing storages 170-180. Continuing with the example above, process 1200 identifies matrix 900, hierarchy of locations 1000, and hierarchy of categories 1100.

Process 1200 then determines, at 1230, an aggregate collection of questions based on the matrix, the hierarchy of categories, and the hierarchy of locations. In some embodiments, process 1200 determines the set of suppliers by identifying the element in the matrix associated with the location and the category and traversing through the matrix according the hierarchy of categories and the category of locations. In different embodiments, process 700 uses different techniques for determining the aggregate collection of questions. The following will describe one technique.

Continuing with the above example, process 1200 may determine the aggregate collection of questions by first identifying the element in matrix 900 associated with the California location and the IT category. FIGS. 13A-13F illustrate an example traversal through matrix 900 illustrated in FIG. 9 based on the hierarchies illustrated in FIGS. 10 and 11 according to some embodiments. As shown in FIG. 13A, the element in this example is at column 940 and row 965 of matrix 900, as highlighted in FIG. 13A. If any sets of questions are associated with this element (which none are in this example), process 1200 includes the sets of questions in the aggregate collection of questions.

Next, process 1200 identifies the descendants of the category based on the hierarchy of categories 1100. Specifically, process 1200 identifies the category in the hierarchy of categories 1100 and traverses down the hierarchy of categories 1100 to identify descendant categories of the category. For this example, process 1200 identifies the IT service category, the network security category, IT equipment category, the laptop category, the desktop category, and the printer category as the descendants of the IT category. Process 1200 then traverses the rows of the current column in matrix 900 according to the identified descendant categories and identifies any sets of questions associated with the elements along the traversal. In this example, process 1200 traverses from the element at column 940 and row 965 to the elements at column 940 and row 970 (IT service in California), column 940 and row 980 (network security in California), column 940 and row 975 (IT equipment in California), column 940 and row 985 (laptops in California), column 940 and row 990 (desktops in California), and column 940 and row 995 (printers in California), as illustrated in FIG. 13B. If any sets of questions are associated with any of the traversed elements, process 1200 includes the sets of questions in the aggregate collection of questions. In this example, process 1200 includes the set of questions QS2 and the set of questions QS3 in the aggregate collection of questions.

To determine the next element to which process 1200 traverses, process 1200 identifies a descendent location of the requested location that has not been traversed based on the hierarchy of locations 1000. In particular, process 1200 identifies the requested location in the hierarch of locations 1000 and traverses down the hierarchy of locations 1000 to identify a descendant location. In this example, process 1200 identifies the San Francisco location as a descendant of the California location. Process 1200 then traverses to the element in the matrix associated with the descendant location and the requested category. As shown in FIG. 13C, process 1200 traverses to the element at column 990 and row 965 (IT in San Francisco) in matrix 900 in this example.

Next, process 1200 traverses the rows of column 950 in a similar manner as traversing the rows of column 940. That is, process 1200 identifies the descendants of the requested category based on the hierarchy of categories 1100, traverses the rows of the current column in matrix 900 according to the identified descendant categories, and identifies any sets of questions associated with the elements along the traversal. For this example, process 1200 traverses from the element at column 950 and row 965 to the elements at column 950 and row 970 (IT service in San Francisco), column 950 and row 980 (network security in San Francisco), column 950 and row 975 (IT equipment in San Francisco), column 950 and row 985 (laptops in San Francisco), column 950 and row 990 (desktops in San Francisco), and column 950 and row 995 (printers in San Francisco), as shown in FIG. 13D. Again, if any sets of questions are associated with any of the traversed elements, process 1200 includes the sets of questions in the aggregate collection of questions. In this example, the set of questions QS2 is associated with a traversed element. However, the set of questions QS2 has already been included in the aggregate collection of questions, as explained above. Thus, process 1200 does not include any sets of questions in the aggregate collection of questions.

Process 1200 determines the next element to traverse to in a similar way as described above. That is, process 1200 identifies a descendent location of the requested location that has not been traversed based on the hierarchy of locations 1000 and then traverses to the element in the matrix associated with the descendent location and the requested category. In this example, process 1200 identifies the Los Angeles location as a descendant of the California location that has not been traversed based on the hierarchy of locations 1000. Thus, process 1200 traverses to the element at column 955 and row 965 (laptops in the world) in matrix 900 in this example, as shown in FIG. 13E.

Process 1200 then traverses the rows of column 955 in a similar manner as traversing the rows of columns 940 and 950. That is, process 1200 identifies the descendants of the requested category based on the hierarchy of categories 1100, traverses the rows of the current column in matrix 900 according to the identified descendant categories, and identifies any sets of questions associated with the elements along the traversal. In this example, process 1200 traverses from the element at column 955 and row 965 to the elements at column 955 and row 970 (IT service in Los Angeles), column 955 and row 980 (network security in Los Angeles), column 955 and row 975 (IT equipment in Los Angeles), column 955 and row 985 (laptops in Los Angeles), column 955 and row 990 (desktops in Los Angeles), and column 955 and row 995 (printers in Los Angeles), as illustrated in FIG. 13F. Again, if any sets of questions are associated with any of the traversed elements, process 1200 includes the sets of questions in the aggregate collection of questions. For this example, the set of questions QS2 is associated with a traversed element. However, the set of questions QS2 has already been included in the aggregate collection of questions, as explained above. Thus, process 1200 does not include any sets of questions in the aggregate collection of questions.

Process 1200 determines the next element to traverse to in a similar way as described above. That is, process 1200 identifies a descendent location of the requested location that has not been traversed based on the hierarchy of locations 1000 and then traverses to the element in the matrix associated with the descendent location and the requested category. In this example, there are no more descendant locations of the California location that have not been traversed based on the hierarchy of locations 1000. Thus, process 1200 determines the aggregate collection of questions as the sets of questions associated with the elements traversed during the traversal through matrix 900. For this example, the aggregate collection of questions includes the set of questions QS2 and the set of questions QS3.

Returning to FIG. 12, after determining the aggregate collection of question, process 1200 generates, at 1240, the aggregate collection of questions based on the determination. Next, process 1200 sends, at 1250, the aggregate collection of questions to the candidate supplier. In some embodiments, process 1200 sends the aggregate collection of question to the candidate supplier when a user of a client device 165 logs onto the portal provided by supplier network manager 150 using an account associated with the candidate supplier.

Process 1200 then receives, at 1260, answers to the aggregate collection of questions from the candidate supplier. Once process 1200 receives the answers, process 1200 sends the answers to the aggregate collection of questions to the computing system. Finally, process 1200 receives, at 1280, approval from the computing system to qualify the candidate supplier. Once process 1200 receives approval from the computing system, process 1200 may add the candidate supplier to a matrix (e.g., matrix 400) used to organize suppliers associated with master data of the computing system.

In some embodiments, a user of the computing system may approve a candidate supplier for a particular supplier level (e.g., a level one supplier, a level two supplier, a level three supplier, etc.) in addition to a location and category. This allows a user of a computing system 105 to segregate between different suppliers at a given location and category according to the supplier level of the suppliers. In some embodiments, supplier network manage 150 stores the supplier level along with the suppliers in the matrix used to organize the suppliers. In this manner, supplier network manager 150 to provide suppliers with different supplier levels when supplier network manager 150 receives requests from a user of a computing system 105.

The embodiments and examples described above by reference to FIGS. 4-13 demonstrate supplier network manager 150 organizing suppliers based on locations and categories. One of ordinary skill in the art will appreciate that the supplier network manager 150 may organize suppliers based on additional and/or different characteristics or qualities associated with suppliers (e.g., level of risk associated with suppliers). For instance, supplier network manager 150 may organize suppliers based on n criteria. In some embodiments, supplier network manager 150 may organize suppliers based on n criteria using an n-dimensional matrix and n number of defined hierarchies for each of the n criteria.

FIG. 14 illustrates an exemplary computer system 1400, in which various embodiments may be implemented. For example, computer system 1400 may be used to implement computing systems 105 and/or supplier network manager 150. Computer system 1400 may be a desktop computer, a laptop, a server computer, or any other type of computer system or combination thereof. Some or all elements of master data manager 115 in FIG. 1, or combinations thereof can be included or implemented in computer system 1400. In addition, computer system 1400 can implement many of the operations, methods, and/or processes described above (e.g., processes, 300, 700, and 1200). As shown in FIG. 14, computer system 1400 includes processing subsystem 1402, which communicates, via bus subsystem 1402, with input/output (I/O) subsystem 1408, storage subsystem 1410 and communication subsystem 1424.

Bus subsystem 1402 is configured to facilitate communication among the various components and subsystems of computer system 1400. While bus subsystem 1402 is illustrated in FIG. 14 as a single bus, one of ordinary skill in the art will understand that bus subsystem 1402 may be implemented as multiple buses. Bus subsystem 1402 may be any of several types of bus structures (e.g., a memory bus or memory controller, a peripheral bus, a local bus, etc.) using any of a variety of bus architectures. Examples of bus architectures may include an Industry Standard Architecture (ISA) bus, a Micro Channel Architecture (MCA) bus, an Enhanced ISA (EISA) bus, a Video Electronics Standards Association (VESA) local bus, a Peripheral Component Interconnect (PCI) bus, a Universal Serial Bus (USB), etc.

Processing subsystem 1402, which can be implemented as one or more integrated circuits (e.g., a conventional microprocessor or microcontroller), controls the operation of computer system 1400. Processing subsystem 1402 may include one or more processors 1404. Each processor 1404 may include one processing unit 1406 (e.g., a single core processor such as processor 1404-1) or several processing units 1406 (e.g., a multicore processor such as processor 1404-2). In some embodiments, processors 1404 of processing subsystem 1402 may be implemented as independent processors while, in other embodiments, processors 1404 of processing subsystem 1402 may be implemented as multiple processors integrate into a single chip or multiple chips. Still, in some embodiments, processors 1404 of processing subsystem 1402 may be implemented as a combination of independent processors and multiple processors integrated into a single chip or multiple chips.

In some embodiments, processing subsystem 1402 can execute a variety of programs or processes in response to program code and can maintain multiple concurrently executing programs or processes. At any given time, some or all of the program code to be executed can reside in processing subsystem 1402 and/or in storage subsystem 1410. Through suitable programming, processing subsystem 1402 can provide various functionalities, such as the functionalities described above by reference to processes 300, 700, and 1200, etc.

I/O subsystem 1408 may include any number of user interface input devices and/or user interface output devices. User interface input devices may include a keyboard, pointing devices (e.g., a mouse, a trackball, etc.), a touchpad, a touch screen incorporated into a display, a scroll wheel, a click wheel, a dial, a button, a switch, a keypad, audio input devices with voice recognition systems, microphones, image/video capture devices (e.g., webcams, image scanners, barcode readers, etc.), motion sensing devices, gesture recognition devices, eye gesture (e.g., blinking) recognition devices, biometric input devices, and/or any other types of input devices.

User interface output devices may include visual output devices (e.g., a display subsystem, indicator lights, etc.), audio output devices (e.g., speakers, headphones, etc.), etc. Examples of a display subsystem may include a cathode ray tube (CRT), a flat-panel device (e.g., a liquid crystal display (LCD), a plasma display, etc.), a projection device, a touch screen, and/or any other types of devices and mechanisms for outputting information from computer system 1400 to a user or another device (e.g., a printer).

As illustrated in FIG. 14, storage subsystem 1410 includes system memory 1412, computer-readable storage medium 1420, and computer-readable storage medium reader 1422. System memory 1412 may be configured to store software in the form of program instructions that are loadable and executable by processing subsystem 1402 as well as data generated during the execution of program instructions. In some embodiments, system memory 1412 may include volatile memory (e.g., random access memory (RAM)) and/or non-volatile memory (e.g., read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), flash memory, etc.). System memory 1412 may include different types of memory, such as static random access memory (SRAM) and/or dynamic random access memory (DRAM). System memory 1412 may include a basic input/output system (BIOS), in some embodiments, that is configured to store basic routines to facilitate transferring information between elements within computer system 1400 (e.g., during start-up).
